The growing demand for energy in electric systems has resulted in major operational difficulties related to voltage level control. This has led specialists to deal more strictly with the control of reactive power and voltage, mainly in the case of radial electric systems supplying seasonal loads. Amongst a variety of commercial solutions to provide voltage regulation arise the static compensators. These represent an alternative of great potential to control the power flow and improve the voltage profile of electric systems. In this context, the SCRSC or Saturated Core Reactor Static Compensator - made up of a magnetic core with special characteristics and capacitors in series and in parallel - becomes an interesting alternative, when compared to other types of equipment. The main advantages related to this product are: robustness, low cost, lower maintenance requirements and good performance. Within this scenario, the purpose of the present dissertation is to carry on further investigation related to a more comprehensive model and computational studies of transient, dynamic and steady state performance of an overall electrical system. Using a given system several studies are performed so as to highlight the equipment energization phenomena as well as the device effectiveness at compensating for system operational condition changes that require the use of voltage regulators to accomplish the power utility standards.
